About

Backend, frontend and the cluster underneath.

I'm a full-stack engineer who likes owning a feature from the database to the pixel. I've spent fourteen years shipping web applications in Java, Spring and React, led front-end teams, and lately I work deep in Kubernetes: distributed platform features, controllers, CI/CD and the console on top. On the side I write Rust and publish open-source tools other people actually install.

Ask

Ask about my experience.

Type the question you would ask in a screening call. A small language model running in your browser finds the parts of my CV that answer it.

Runs on your device · model loads when you start typing

How this works
  1. At build time my CV is split into ~50 short passages, and each is turned into a 384-number vector by all-MiniLM-L6-v2.
  2. Your question is embedded by the same model, in your browser through WebAssembly. No server and no API key.
  3. Passages are ranked by cosine similarity plus a small keyword boost. The best matches are shown with their source.

Questions are logged anonymously so I can see what people want to know.
